PDC Conical Reaming Drill Bit

Common specifications: φ94/113, φ113/153, φ96/153, φ120/153, φ153/203, φ120/245, φ203/245, φ245/275, φ275/315, etc. Other specifications and special requirements can be customized according to specific requirements.

The conical reaming drill bit is mainly composed of PDC cutting teeth and the drill bit body. It can ream the hole to the designed diameter in one or more times. Compared with the multiple hole-forming process, its efficiency is greatly improved. It is suitable for drilling in soft to medium-hard formations and is not suitable for use in broken, fractured, or highly abrasive formations.
